8LS2 Ch4 Test Review - Reproduction & Genetic Variation

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four genetically diverse gametes (sperm or eggs).

Front

What is the primary function of meiosis?

Back

To reduce the chromosome number by half and produce gametes.

Front

What is a gamete?

Back

A gamete is a reproductive cell (sperm or egg) that carries half the genetic information of an organism.

Front

What is asexual reproduction?

Back

Asexual reproduction is a mode of reproduction that involves a single parent, resulting in offspring that are genetically identical to the parent.

Front

What is sexual reproduction?

Back

Sexual reproduction is a mode of reproduction that involves two parents, combining their genetic material to produce genetically diverse offspring.

Front

Why is reproduction important for organisms?

Back

Reproduction is important because it ensures new individuals are produced, preventing extinction.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals, which can lead to different traits.

Front

How do offspring inherit traits in asexual reproduction?

Back

Offspring in asexual reproduction are genetically identical to the parent.

Front

How do offspring inherit traits in sexual reproduction?

Back

Offspring in sexual reproduction inherit a mix of traits from two parents.

Front

What would happen if gametes did not undergo meiosis before fertilization?

Back

Offspring would inherit twice the necessary number of chromosomes, leading to genetic instability.
